What is a "common" situation?
Being single, married, divorced, in several sexual relationships at once are all common - they all have different implications for inheritance. Does your state treat same-sex relationships the same as heterosexual relationships for inheritance - how does that impact the will? What is your relationship status today? Is there no possibility that it will change before you die - which could be tomorrow or 60 years from now.
How many children do you have? Will you have more (or less) when you die? How have you dealt with that?
What if the executor of your estate dies before you do? Or doesn't want to do it when the time comes? Or values their time for doing it at $1,200 per hour payable from the estate?
What form of title is any land you own held in? Do you know how that affects your estate?
No one has a "common" situation.
